I got my Gladiators Sanctum to level 3, and tried out the Highmaul Coliseum thing.   You get invited by this guy:

Who seems to be, as my kids use to say “SUCH the jerk!”.   I mean look at those poor Draenei.

You can’t stealth in there, or at least in stealth everyone can see you.  I got jumped on right away and died first.

On the plus side, we won Ashran twice, and between that and my sanctum, I have 1400/1700 CP in like a day.

I like this guys dialog too.  Sounds like me.
